Abstract

The invention discloses a stable starch-based film-forming composition, which comprises natural amylose, natural amylopectin, modified starch and a reinforcing agent. The starch film made by using the composition has good moisture retention, is not easy to age, The advantage of excellent toughness.

Description

technical field [0001] The invention relates to a stable starch-based film-forming composition, which belongs to the field of deep processing of starch and starch derivatives. Background technique [0002] Native or modified starches are often used in the food or pharmaceutical processing industries. Through the physical and chemical modification of native starch, it has the characteristics that native starch does not have, such as improved fluidity, water solubility, film-forming property, mechanical strength, etc. [0003] Natural plant starches are structurally divided into two categories: amylopectin and amylose. Amylose is a polysaccharide chain in which D-glucose groups are connected by α-(1,4) glycosidic bonds. There are about 200 glucose groups in the molecule, and the molecular weight is 1 to 2×10 5 , The degree of polymerization is 990, the spatial conformation is coiled into a helical shape, and each rotation is 6 glucose groups. In addition to the sugar chains...
